>>> np.random.zipf(np.nan)
# hangs forever, doesn't respond to ctrl C
>>> np.random.zipf(1.0000000000001)
# hangs for a possibly finite but very long time, also not responding to Ctrl+C
The former should probably just throw an exception. The latter is sort of inevitable with a rejection algorithm, but if we called PyErr_CheckSignals() then at least it could be cancelled.
